At an observation time of \(3\bar{\tau }_{\rm eq}\) , nearly all points of \(C_1\)  coincide. Deviations of the two colored points in \(C_2\)  are modest. Deviations increase drastically in \(C_3\)  and \(C_4\) . This proves that relaxation time varies with observables. Relaxation times for higher order cumulants are larger, consistent with expectations [1]}. When low order cumulants have reached their equilibrium expectations, high order cumulants may have not reached equilibrium expectations yet.
